Cheap and can be cut to the size desired........
Not idea when compared to the much closer spaced fins of sinks we'd use on chips, but would help cool the pump at pretty low cost none the less.
Those and a monster core should do alot to make that MD30 a viable option. Monster pump to use with monster core......seems like right to me! :D

25W does'nt make much difference, but the md-30 is ~50W.
Also, a gpu would hardly be putting out 100W, 60W at maximum, probably much less. Look as the size of the heatsinks on them and compare it to a cpu one. Consider also the slow fans they put on them.
While flow is proportional to performance, the relationship is not linear and has harsh diminishing returns. Ie a doubling of flow will not equal a doubling of performance.
Consequently the extra flow offered by a powerfull pump is high in the diminishing returns part of the components curves, so the extra hydrolic power inputted by the pump is negligable at best. It is still there of course, but the heat can start to negate or at worst overpower the gains.
For a typical overclocked system, lets say 150W from cpu + gpu, add an md-30, and you are adding 33% more heat. Can you see why you need an uber rad to deal with it now? (a bip-II will 'deal with it', but you will be worse off)
You are quite correct in your statement:
"If your radiator can't handle an extra 25 watts of heat I think it needs an upgrade"
150 from a CPU + GPU? are you kidding me? I'm not sure about the 7800GTX but after vmods and OCing it has to be somewhere over 100 watts and an FX57 is around 100 watts stock. At 2.9-3ghz and 1.7V+ you're putting out 150 watts at least I'd say. And if these storm G4/G5 blocks are as flow dependant as you say they should benefit well from the added flow.
Ok so the iwakis everyone else uses are 15-20 watts of heat and this one is 50 watts. Still only 30-35 watts more. Your radiator should have enough overhead to handle that.
afire, look at the performance curves of a G4. any flow over 2 GPM yeilds virtually nothing. doubling flow nets only a tiny fraction of a change in temperature, while also increasing water temp because of the larger pump, and, since the water temp is raised more than the waterblock's cooling power goes down (regardless of what radiator you have), your overall temps go up. Even if you have a massive radiator, the room will heat up quicker, get hotter, resulting in, once again, warmer water.
